i bought a toshiba laptop with windows vista. i'e had the thing for about 3 weeks and recently it developed this annoying issue. when i open up a window the borders begin to flash and its like the window is being refreshed over and over again and it stops responding to the mouse when it flashes. the same thing happens with the quicklaunch icons, internet explorer, all folders windows, messenger windows, almost everything. it keeps doing it every couple of seconds, but if the window is in full screen it doesnt do anything but flash the border.
can anyone tell me wht this is and what i can do to fix it?
